摘要
结合岩溶地区某运营双线铁路路基的坍塌,有针对性地对塌陷地段路基采用地质雷达进行探测,确定了路基中的岩溶通道和溶洞的位置及特征;采用注浆的方法对该地段路基进行了加固,并以地质雷达进行验证,证明注浆用于岩溶路基的处理效果显著。
Combining with the subgrade collapse of double track railway in operation in karst region, the subgrade in the section collapsed is prospected with geological radar to confirm the location and characteristics of karst passage and cave in the subgrade, and then it is reinforced by grouting. Geological radar will be used for the purpose of verification so as to prove the outstanding effect of grouting on karst subgrade treatment.
